IMPROVEMENT IN MACHINES FOR LAVING OUT SASH.

Speciiication forming part of Letters Patent No. 116,602, dated July 4, 1871.

To all whom it may concern:

Be it known that I, JOHN N. KIKENDALL, Jr., of Virginia, in the county oi' Cass and State of Illinois, have invented a new and Improved Machine for Laying Oii' Sash, and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the san1e,ref erence being had to the accompanyii1g drawing forming part of this speciiication.

This invention relates to improvements in maj chines for laying off sash, and'it consists in a pair of rods, carrying adjustable cutters, arranged above a table, on which the bars to be laid oit' are placed to work reciprocally toward and from each other and the table by the action of a foot-lever and a spring, for cuttingor marking both sides at once, by pinching the barbetween them, all as hereinafter described.

Figure 1 is an end elevation of my improved machine. Fig. 2 is a top view Fig. b is a crosssection through the bars and the table. Fi 4 is a side elevation of one of the knives and clamp for attaching it to the rods, and Fig. 5 is a section through Fig. 4.

Similar letters of referenceindicate corresponding parts.

A is a long narrow table mounted on any suitable stand, and provided with a gauge, B, for the end of the bar, made adjustable lengthwise of the table; also, provided with one or more gauges, O, adjustable transversely of the table for holding the sash-bars to be laid oli' in. the center of the table, being pressed or held against the vertical parts of the said gauges by hand or etherwise. D represents the rods which carry the cutters C. They are mounted in the upper ends of the curved levers E, which are pivoted to the stand at F, and connectedto the foot-treadle H by rods G, as shown, there heilig' one pair of said levers at each end ofthe machine for suliiporting the said bars at each end. lThe sash-bars to be laid out are placed on the table with one end against gauge B, by which they are held in the right position relatively to the cutters in the lengthwise direction, and the said cutters, bein g also adjusted properly on the rods' Dirom the end of the bar and from each other, are brought up against the sides simultaneously, marking both at once. rlhe treadle is raised and the bars moved back by a coiled spring. rIhe cutters are made convex on the cutting-ed ges, as shown, and they are attached to the rods by tubes a and setscrews b, so that they may be turned on the said rods, as well as shifted along lengthwise, for causing the blades to project more or less toward the bar to be acted upon, according to whether it be thick or thin. Instead of securingthe cutter-tubes to the rods by the set-screw b they may be divided and be clamped upon the rods by the screws e passing through ears f.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. lhe combination, with the table A, having gauges B and C, of the rods I) and adjustable cutters C thereon, constructed to move reciprocally toward or from each other and the table, substantially as specified.

2. rIhe rods carrying the cutters mounted in a pair of curved arms, E, pivoted together and to the table at each end, a-nd operated by atreadle, H, and spring, all substantially as specified.
